Semiconductor fabrication continues to challenge and push the realm of automated, ultra-clean manufacturing. The slightest amount of contamination, from ambient air to dust, could scrap a $100,000+ wafer. Glass-to-metal (GTM) hermetic seals for wire feedthroughs have been the usual option for transmitting power, control and monitoring signals. But these seals can be constrained in size,…
Coiled Pins for High-Impact Loads
By Jonathan Higgins, Field Applications Engineer, Spirol International Corp., Danielson, Conn.

A coupler manufacturer was asked to design a stop feature that could withstand high impact loads for construction…
New Stepper Motors Beat Corrosion Without Seals
A new design technique produces corrosion-proof and waterproof stepper motors, extending motor life in harsh outdoor conditions. Electric motors used outdoors are susceptible to temperature extremes and moisture build up, leading to internal corrosion that quickly shortens motor life, causing early motor failure. However, a new approach to preventing corrosion and early failure uses a…
